What is functional diversity?

  1. The number of different species in an ecosystem

  2. The variety of traits and functions performed by different species in an ecosystem

  3. The evenness of species abundances in an ecosystem

  4. The degree of specialization of species in an ecosystem


Correct Option: B
Explanation:

Functional diversity refers to the range of traits and functions that different species perform in an ecosystem. It is a measure of the diversity of ecological roles played by species in a community.

How can functional diversity affect ecosystem functioning?

  1. It can increase the stability of ecosystem processes

  2. It can increase the efficiency of resource use

  3. It can increase the resilience of ecosystems to disturbances

  4. All of the above


Correct Option: D
Explanation:

Functional diversity can affect ecosystem functioning in a number of ways. It can increase the stability of ecosystem processes by providing multiple species that can perform the same function. It can increase the efficiency of resource use by allowing different species to specialize on different resources. It can also increase the resilience of ecosystems to disturbances by providing a buffer against the loss of any one species.

Which of the following is not a component of functional diversity?

  1. Species richness

  2. Species evenness

  3. Functional traits

  4. Functional redundancy


Correct Option: A
Explanation:

Species richness is a measure of the number of different species in an ecosystem, while functional diversity is a measure of the variety of traits and functions performed by different species in an ecosystem. Functional traits are the characteristics of species that affect their function in an ecosystem, and functional redundancy is the degree to which different species can perform the same function.

How can climate change affect functional diversity?

  1. It can cause the loss of species with certain functional traits

  2. It can alter the relative abundance of different species

  3. It can change the interactions between species

  4. All of the above


Correct Option: D
Explanation:

Climate change can affect functional diversity in a number of ways. It can cause the loss of species with certain functional traits, such as those that are adapted to cold climates. It can also alter the relative abundance of different species, as some species may be more able to tolerate the effects of climate change than others. Finally, climate change can change the interactions between species, as the distribution and abundance of species can change in response to climate change.

What are some of the consequences of a loss of functional diversity in ecosystems?

  1. Decreased ecosystem stability

  2. Decreased ecosystem productivity

  3. Increased vulnerability to disturbances

  4. All of the above


Correct Option: D
Explanation:

A loss of functional diversity in ecosystems can have a number of negative consequences. It can decrease ecosystem stability by reducing the number of species that can perform the same function. It can also decrease ecosystem productivity by reducing the efficiency of resource use. Finally, it can increase the vulnerability of ecosystems to disturbances by reducing the buffer against the loss of any one species.

What are some ways to promote functional diversity in ecosystems?

  1. Conserving and restoring habitats

  2. Reducing pollution

  3. Managing invasive species

  4. All of the above


Correct Option: D
Explanation:

There are a number of ways to promote functional diversity in ecosystems. Conserving and restoring habitats can help to protect the species that perform important functions in ecosystems. Reducing pollution can help to reduce the negative effects of pollution on species and their functions. Managing invasive species can help to prevent the spread of species that can disrupt the functioning of ecosystems.

Which of the following is an example of a functional trait?

  1. Body size

  2. Diet

  3. Reproductive strategy

  4. All of the above


Correct Option: D
Explanation:

Functional traits are the characteristics of species that affect their function in an ecosystem. Body size, diet, and reproductive strategy are all examples of functional traits that can affect the role that a species plays in an ecosystem.

What is the term for the degree to which different species can perform the same function in an ecosystem?

  1. Functional redundancy

  2. Functional complementarity

  3. Functional diversity

  4. Functional richness


Correct Option: A
Explanation:

Functional redundancy is the degree to which different species can perform the same function in an ecosystem. It is a measure of the extent to which the loss of one species can be compensated for by the presence of other species that can perform the same function.

How can functional diversity be measured?

  1. By measuring the number of different species in an ecosystem

  2. By measuring the abundance of different species in an ecosystem

  3. By measuring the traits of different species in an ecosystem

  4. By measuring the interactions between different species in an ecosystem


Correct Option: C
Explanation:

Functional diversity can be measured by measuring the traits of different species in an ecosystem. Functional traits are the characteristics of species that affect their function in an ecosystem.

Which of the following is not a potential consequence of a loss of functional diversity in ecosystems?

  1. Increased ecosystem stability

  2. Increased ecosystem productivity

  3. Increased resilience to disturbances

  4. Decreased vulnerability to climate change


Correct Option: A
Explanation:

A loss of functional diversity in ecosystems can have a number of negative consequences, including decreased ecosystem productivity, increased vulnerability to disturbances, and decreased resilience to climate change. However, it is not likely to lead to increased ecosystem stability.

Which of the following is an example of a functional group?

  1. All carnivores in an ecosystem

  2. All herbivores in an ecosystem

  3. All plants in an ecosystem

  4. All animals in an ecosystem


Correct Option: A
Explanation:

A functional group is a group of species that share similar functional traits and perform similar roles in an ecosystem. All carnivores in an ecosystem form a functional group because they share the trait of being predators and they perform the role of consuming prey.

How can functional diversity affect the resilience of ecosystems to climate change?

  1. It can provide a buffer against the loss of any one species

  2. It can allow ecosystems to adapt to changing environmental conditions

  3. It can increase the efficiency of resource use

  4. All of the above


Correct Option: D
Explanation:

Functional diversity can affect the resilience of ecosystems to climate change in a number of ways. It can provide a buffer against the loss of any one species by ensuring that there are other species that can perform the same function. It can also allow ecosystems to adapt to changing environmental conditions by providing a range of traits that can be selected for in response to new conditions. Finally, it can increase the efficiency of resource use by allowing different species to specialize on different resources.

Which of the following is not a way to promote functional diversity in ecosystems?

  1. Conserving and restoring habitats

  2. Reducing pollution

  3. Introducing invasive species

  4. Managing invasive species


Correct Option: C
Explanation:

Introducing invasive species is not a way to promote functional diversity in ecosystems. Invasive species can disrupt the functioning of ecosystems by competing with native species for resources and by altering the interactions between species.

Which of the following is an example of a functional trait that is related to resource use?

  1. Body size

  2. Diet

  3. Reproductive strategy

  4. Dispersal ability


Correct Option: B
Explanation:

Diet is an example of a functional trait that is related to resource use. Diet determines the types of resources that a species consumes and the way that it interacts with other species in the ecosystem.

How can functional diversity affect the stability of ecosystem processes?

  1. It can increase the number of species that can perform the same function

  2. It can decrease the number of species that can perform the same function

  3. It can have no effect on the number of species that can perform the same function

  4. It can increase the number of species that can perform different functions


Correct Option: A
Explanation:

Functional diversity can affect the stability of ecosystem processes by increasing the number of species that can perform the same function. This means that if one species is lost, there are other species that can take its place and perform the same function. This helps to ensure that ecosystem processes continue to function even if there are changes in the species composition of the ecosystem.
